[🐞] V2 Router: head() override order is wrong

[devcaeg]

Which component is affected?

Qwik Runtime

Describe the bug

When using Qwik v2 with nested layouts, defining Head with title and description in a deeper layout does not override the values defined in a higher layout. The browser keeps the outer layout’s title/description. This seems to contradict the docs for nested layouts & Head.

https://qwik.dev/docs/pages/#nested-layouts-and-head

The docs imply head content from nearer (deeper) layouts/pages should take precedence when merged.

Expected behavior

On a route rendered by a deeper layout, the title and description from that deeper layout’s should be applied (or at least take precedence over the outer layout’s values).

@devcaeg do you have reproduction?

@Varixo @wmertens

I have added a reproduction.

As you can see on the home page, the meta title is “Title default,” and on the “/test” page, the meta title should be “Test 2,” but it still says “Title default.”

[wmertens]

actually, this also happens in v1, and it's intended. The idea is that earlier head() calls can wrap nested ones.

I suppose we could also have a middleware approach but that would require a RFC.
